Stoke have completed the £2.5million signing of United States winger Brek Shea from FC Dallas.
Shea has signed a four-and-a-half year contract at the Britannia Stadium after the club made a successful appeal for a work permit on Thursday.
Stoke boss Tony Pulis told the club's official website: "It's fantastic news that we have been able to push through a deal."
He added: "Brek is a very, very exciting player, and one who we firmly believe could go on to become an outstanding player for this football club.
"He has terrific pace, a very good left foot and is capable of scoring goals. He has all the tools needed to be a success here."
Shea is the Potters' first signing of the January transfer window.
